Quotes from Reffo's # 51:
Wanting the settlements proves nothing.
Reffo: It is not just "wanting the settlements". Said settlements do not stand on thin air, they are built on the land and establishing a settlement means
getting hold of the place where they are built. They are not established with the intention of grabbing land temporarily but with the hope of holding it for good. The idea behind the creation of settlements and outposts all over the West Bank is to establish so many 'facts on the ground' that eventually there would be no room left for a viable Palestinian State. I would challenge anyone here to argue that the aim of the settlement enterprise in the WB is not to get hold of all of it.
Yes, most Israelis then want the settlements because most of the areas on which the major "settlements" are built were areas that were owned and inhabited by Jews prior to 1948. But wanting the settlements is not the same as wanting all the land between the river and the sea, even though Israel would be entitled to that too. In fact, the willingness of Israel to compromise on that was demonstrated in 1947, 2000/2001, 2008 when Israel accepted less and offered formal peace deals to the Palestinian Arabs on borders which did not include all the land between the river and the sea. None of those offers were accepted by the Arabs.
That the areas where major settlements (and what about the minor ones?) are built were areas inhabited by Jews prior to 1948, is just one of the various reasons 'why' the settlers and their supporters 'want all the land'. Since the settlement enterprise has been carried out with the overt or covert support of successive Israeli administrations it may be said that procuring 'all the land' between the Jordan and the sea has been part of continued Israeli policy.
